Figure 7. Activity of Prelimbic/Cingulate Neurons during Over-Training.
(A and B) Normalized ensemble activity of PL units in superficial (PLs, A) and deep (PLd, B) layers from early to late over-training (stages 5–11).
(C and D) Baseline-subtracted raw firing activity of task-related (C) and non-task-related (D) units, separated by early over-training (blue, stages 5–8) and late over-training (red, stages 9–11). Turn-related activity in superficial layers, and pan-run activity in deep layers, declined as over-training progressed. *p < 0.05.
